BUILDING STRUCTURE COMPRISING WATER RECEPTORS.

Application filed December 30, 1926.

In modern building practice it is customary to build bath tubs, or shower receptors into the wall. rI`his is done by setting the preformed lub or other article against the unfinished wall, and then applying cement against the wall which extends down against the upper surface et the tub. 'lhe wall is usually tinishcd b v applying tile or plaster ouh-Iide of the cement.

The tub is relatively heavy. and as the building grows older thc tub tends to settle. This is particularly true it a solid porcelain tub is used` but is also true where the tub is made ot' porcelain covered metal. This settling is apt 'to leave a crack between the bottoni ot the tile or plaster at the top tace of the tub. thri'iugh which water may leak into the wall.

(lne of the ditlicultics to be niet in overcoming this detect is the tact that it is highlyA inadvisahle to anchor the tub to the upper portion ot the wall. tor it this is done the weight ot' the tub will tend to cracl-z the cement hacking and displace the tiles.

I have discovered that a substantially water-proof union can be made between the tub or other article and the wall. it such article, (which lor convenience I call a water receptor. intending to embrace within this term both solid poreclain and enamel covered plumbing fixtures ot various types adapted to receive water such tubs, shower receptors, sinks and the like) is lornied with a sheet of smooth metal extending upwardly from the upper face ot that portion ot the receptor which is intended to be huilt into the wall. rllhis metal should be tirinly anchored into the receptor, but as stated, it should be smooth, and also should be tiexihle where it extends above the face ot' the receptor. The metal plate should be so positioned that when the wall is inished it is embedded in the cement or plaster backing. Due to the fact that the metal is smooth and flexible, it will not be anchored in the cement of the wall, so that if the tub settles it will move relatively to the cement, and thus will not drag the wall down with the settling tub. The amount of settling is usually not much in excess of one-eighth (1/8) of an inch, and by having the metal plate extended as much as one-halt (l) of an inch above the facing ot the receptor` an ample engagement between the metal and the cement will remain, so that the gap will Serial No. 157,916.

be dammed against the flow of water into the wall.

One ot' the principal reasons tor making the metal flexible is the fact that in shipment the metal is very apt to become bent. It stift metal is used it is apt to be lett With waves or rough spots when it is bent back into a verticle position by the plumber who is installing the article. This would tend to anchor the metal to the cement of the wall, which as pointed out is highly inadvisable. It the metal is made ot brass or other appropriate n'ietal, it can be sutliciently Flexible so that the entire plate may be bent down for raised in position when the receptor is lo he built into the wall.

r1the niet-al plate may ber anchored into the ceramic body in any desired way, but in the accompanying drawing I show one method in which this can be done. In the drawing Fig. l shows a cri'iss-secl ion ot a portion ol' a wall into which a bath tub has been built; Fig. 2 shows the same parts after the tub has settled; and Fig. 3 shows a particular torni of metal plate.

The back edge ot the tub which is designated by the numeral 2. is provided with a recess 4 which restricted at the opening. A plate of brass (i is bent into an angle and inserted into a` recess Ll. The recess is then lilled with cement 8, thus firmly anchoring plate G in place. The wall shown comprises the studding 10, metal lath 12, the scratch coat ot plaster 14, and the cement hed lll. which it will be noted surrounds the upper portion ot' the plate 'lhe wall is provided with a tinishing coat 18 which may be tile or plaster.

Fig. 2 shows the saine paris as Fig. l, but after the tub has settled. It will be noted that the plate 6 is still firmly anchored in the recess 4, and has moved relative to the cement 16, but the upper edge of plate G still extends into the cement 16 and serves as a dam for the water.

In Fig. 3, I show a method ot cutting the metal strip 6, so that the strip can be bent to follow curves in the shape of the receptor.

What I claim is:

1. In a building construction a wall, a water receptor of the type described having a portion built into the wall, a recess with a restricted opening formed in the upper face of that portion of the receptor which shipment, and then can readily be lun lof

extends into the wall, a metal plate anchored by cement in said recess and extending upwardly therefrom, and cement, forming part of the wall, embracing the upper portion ot said metal plate but not anchored thereto, whereby a joint iS formed between the receptor and the wall which will provide a water stop both at the time when the receptor is built into the wall and atter relative movement otl the receptor and the wall has taken place.

2. A water receptor of the type described having a portion adapted to be built into a Wall having a metal plate anchored in the upper face of said portion7 and extending above the upper face ot' the receptor, said plate being smooth and flexible, whereby the same may be set in cement without being anchored therein to torni a joint with such cement which will provide a water stop despite relative n'io'vemcnt of the receptor and such cement.

3. A structure defined in claim 2 in which the nietal plate is anchored by cement in a recess formed in the upper tace of the receptor.
